Looking at the Stitching Notes, I've got a
couple of suggestions. First, you need to figure
out how to fix your ISO (white balance) and
exposure time for best results. Second, you'll
need to reduce your Field of View a bit -
currently you've got horizontal overlap of
only 12.3 percent - that's not really enough
for the GigaPan Stitcher to find enough control
points to properly stitch the images. You want to
shoot for an overlap between adjacent photos of
somewhere between 30% and 50%. If you're able
to get these things sorted out I suspect
you'll be considerably more pleased with your
resulting GigaPans.
